Arsenal Medical

Arsenal Medical, founded by George Whitesides and Robert Langer, is a platform technology company developing novel, therapeutic in-situ forming materials. In 2011, Arsenal Medical spun off Lyra Therapeutics to advance our clinical-stage drug delivery system that provides a steady dose of medication directly to diseased tissues. Arsenal Medical is developing a system that injects an in-situ curing elastomeric polymer material to fill and seal the aneurysm sac around stent grafts. The material is designed to flow around the graft and cure into an elastic solid. Filling the sac to cover branch vessels that could cause aneurysm expansion enhances graft sealing to minimize endoleaks, and stabilizes the graft position to prevent migration.
